Preliminary Operations; Purging Non-Condensable Gases - MasterCool 69789-220 Gebrauchsanleitung

INSUFFICIENT GAS ALARM: Beeper and LED advise when the charging quantity set
exceeds the difference between availability and bottle minimum.

PRELIMINARY OPERATIONS

Check that the main switch (i) is set to O. Check that all the MACHINE taps are closed.
Connect the MACHINE to the electrical supply and switch on. Check that the vacuum pump oil
level indicator shows at least one-half full. If the level is lower, add oil as explained in the
MAINTENANCE section. Check that in the new oil container (n) there are at least 100 cc of the
oil recommended by the manufacturer of the vehicle A/C system. Check that the oil level in
tank (m) is < 200 cc. Check on the MACHINE display that there are at roughly 3 kg of
refrigerant in the bottle. Should this not be the case, fill the on-board MACHINE bottle from an
external bottle of appropriate refrigerant following the procedure described in the ROUTINE
MAINTENANCE section.

PURGING NON-CONDENSABLE GASES

Before every use, check if there is air in the bottle: select the DATA MENU and read the bottle
temperature. Compare the bottle pressure with the values given in the table; pull the ring of the
safety valve until the bottle pressure reading corresponds to the values given in the table.
Example: Bottle Temperature = 20°C. The bottle pressure must be brought to 5.2 bars.

- cheek the vacuum pump oil level - press ENTER
- fill the new oil container - press ENTER
- install the tracer cartridge - press ENTER
- assemble the hoses - press ENTER
- connect the quick-connect couplings - press ENTER
- press START to run the vacuum cycle for 1 minute
- fill the on-board bottle (see the instruction manual) - press ENTER
- press START to print the guide - press STOP to exit
Follow the instructions displayed. At the end of the procedure, press START to print a
summary report of the guided procedure. Press STOP to exit.
NOTE: If the guided procedure is not completed, it will be displayed again the next time the
machine is switched on.
